摘要
机载LiDAR点云和倾斜摄影影像是两种新型测绘地理信息数据,可以用来制作DEM、DOM和建筑三维模型。在分析点云数据和倾斜数据基础上,阐述点云和影像数据融合处理的关键步骤和方法。对点云配准、航带裁切、三维建模以及正射影像制作流程进行了详细阐述,开创了两种数据源融合处理的新模式。
Airborne LiDAR point cloud and oblique photographic image are two type of new surveying,mapping and geographic information data.That can be used to make the DEM,DOM and 3D Building Models.Based on the analysis of point cloud and oblique images,the key steps and methods of the fusion processing of point cloud and oblique image data are described.This paper elaborates on the points cloud matching,the flight line cutting,the building 3D modeling and the DOM producing process work flow.It creates a new model for the fusion of the two data sources.
